Continuity: While Dick is in the Champion's Club, he is up on the table, acting like a puppet. He knocks the pepper shaker off the table with his foot. After the camera switches shots, it returns to Dick, who knocks the shaker off the table again.

Revealing: When we see Jane spotting her friends you can see a Nissan Xterra. But the one shown is a 2003-2004 model, but this movie takes place in 2000.

Visible crew/equipment: The first day Dick is home after losing his job he, opens the fridge and the light reflects in his eyes. There are three white reflections in his eyes instead of just one in the center.

Continuity: When Jack McCallister climbs into the helicopter and closes the door, his jacket was unzipped. A split second later in the next shot when he salutes Dick and the helicopter takes off, his jacket is zipped up, his seat harness is fastened, and he is wearing hearing protection. One might argue that he zipped up and buckled up between shots that we didn't see, but there was no break in the audio track between the two shots.

Continuity: When Dick and Jane go through the puddle after robbing the store with the black lights in them, it shows an exterior shot of Dick with his hood up. In the immediate interior shot, his hood is back down.

Factual error: When Dick robs the store, a sign on the cash register reads "You must be born after this date in 1983 to buy beer." Since the legal drinking age is 21, that would mean the movie is set in 2004. However, the film states that the year is 2000.
